[0074] In the definitions of cyanoalkyl, alkylcarbonyl, alkenylcarbonyl, haloalkenylcarbonyl, alkynylcarbonyl, alkoxycarbonyl, alkylthiocarbonyl and haloalkylcarbonyl, the upper and lower limits of the number of carbon atoms given in each case do not include the cyano or carbonyl carbon atom, as the case may be.

[0075] The compounds of formula I may, in respect of the group W (W1 to W3), be present in the form of mixtures consisting of the isomers substituted in the 3- and 5-positions of the pyrazole ring by the pyridone group (pyridone), for example in the form of regioisomers IW1a and IW1b

H. Wiley, Interscience Publishers, John Wiley & Sons, New York, 1967, page 1 ff.; or in “Comprehensive Heterocyclic Chemistry”, Editors A. R. Katritzky and C. W. Rees, Pergamon Press, Oxford, 1987, or by derivatisation according to known standard methods as described, for example, in “Advanced Organic Chemistry, Third Edition, Editor J. March, John Wiley & Sons, New York, 1985; in “Comprehensive Organic Transformations”, Editor R. C. Larock, VCH Publishers, Inc., New York, 1989; or in “Comprehensive Organic Functional Group Transformations”, Editors A. R. Katritzky, O. Meth-Cohn, C. W. Rees, Pergamon Press, Oxford, 1995, or as described in the Patent Specifications EP-A-0 361 114, U.S. Pat. No. 5,032,165, WO 92/02509, WO 92/06962, WO 95/33728 and WO 96/01254.

[0159] The end products of formula I can be isolated in conventional manner by concentration or evaporation of the solvent and purified by recrystallisation or trituration of the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons, by distillation or by means of column chromatography and a suitable eluant. The sequence in which it is advantageous for certain reactions to be carried out so as to avoid possible secondary reactions will also be familiar to the person skilled in the art. Unless the synthesis is specifically aimed at the isolation of pure isomers, the product may be obtained in the form of a mixture of two or more isomers. The isomers can be separated according to methods known per se.

[0160] For the use according to the invention of the compounds of formula I or of compositions comprising them, there come into consideration all methods of application customary in agriculture, for example pre-emergence application, post-emergence application and seed dressing, and also various methods and techniques such as, for example, the controlled release of active ingredient. For that purpose a solution of the active ingredient is applied to mineral granule carriers or polymerised granules (urea/formaldehyde) and dried. If required, it is also possible to apply a coating (coated granules), which allows the active ingredient to be released in metered amounts over a specific period of time.

[0161] The compounds of formula I may be used in unmodified form, that is to say as obtained in the synthesising process, but they are preferably formulated in customary manner together with the adjuvants conventionally employed in formulation technology, for example into emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules or microcapsules. Such formulations are described, for example, in WO 97/34485, pages 9 to 13. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, wetting, scattering or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.

[0162] The formulations, that is to say the compositions, preparations or mixtures comprising the compound (active ingredient) of formula I or at least one compound of formula I and, usually, one or more solid or liquid formulation adjuvants, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredients with the formulation adjuvants, for example solvents or solid carriers. Surface-active compounds (surfactants) may also be used in addition in the preparation of the formulations. Examples of solvents and solid carriers are given, for example, in WO 97/34485, page 6.

[0163] Depending on the nature of the compound of formula I to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants and surfactant mixtures having good emulsifying, dispersing and wetting properties. Examples of suitable anionic, non-ionic and cationic surfactants are listed, for example, in WO 97/34485, pages 7 and 8.

[0164] In addition, the surfactants conventionally employed in formulation technology, which are described in, inter alia, “McCutcheon's Detergents and Emulsifiers Annual” MC Publishing Corp., Ridgewood N.J., 1981, Stache, H., “Tensid-Taschenbuch”, Carl Hanser Verlag, Munich/Vienna 1981, and M. and J. Ash, “Encyclopedia of Surfactants”, Vol. I-III, Chemical Publishing Co., New York, 1980-81, are also suitable for the preparation of the herbicidal compositions according to the invention.

[0165] The herbicidal formulations generally contain from 0.1 to 99% by weight, especially from 0.1 to 95% by weight, of herbicide, from 1 to 99.9% by weight, especially from 5 to 99.8% by weight, of a solid or liquid formulation adjuvant, and from 0 to 25% by weight, especially from 0.1 to 25% by weight, of a surfactant. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations. The compositions may also comprise further ingredients, such as stabilisers, for example vegetable oils or epoxidised vegetable oils (epoxidised coconut oil, rape oil or soybean oil), anti-foams, for example silicone oil, preservatives, viscosity regulators, binders, tackifiers, and also fertilisers or other active ingredients.

[0166] The compounds of formula I can be used successfully either in the form of a mixture comprising the isomers IW1a and IW1b or in the form of pure isomer IW1a or IW1b, generally on plants or the locus thereof, at rates of application of from 0.001 to 4 kg/ha, especially from 0.005 to 2 kg/ha. The concentration required to achieve the desired effect can be determined by experiment. It is dependent on the nature of the action, the stage of development of the cultivated plant and of the weed and on the application (place, time, method) and may vary within wide limits as a function of those parameters.

[0167] The compounds of formula I and, generally, the isomers of formula Ia especially, are distinguished by herbicidal and growth-inhibiting properties, allowing them to be used in crops of useful plants, especially cereals, cotton, soybeans, sugar beet, sugar cane, plantation crops, rape, maize and rice, and also for non-selective weed control.

[0168] “Crops” is to be understood as meaning also crops that have been made tolerant to herbicides or classes of herbicides as a result of conventional methods of breeding or genetic techniques. The weeds to be controlled may be either monocotyledonous or dicotyledonous weeds, such as, for example, Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Phaseolus, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica.

BIOLOGICAL EXAMPLES Example B1: Herbicidal action prior to emergence of the plants (pre-emergence action)

[0528] Monocotyledonous and dicotyledonous test plants are sown in standard soil in plastics pots. Immediately after sowing, the test compounds, each in the form of an aqueous suspension or emulsion prepared from a 25% emulsifiable concentrate (Example F1, c) in WO 97/34485, pages 9 and 10), are applied by spraying at a rate of application of 2000 g of active ingredient/ha (500 liters water/ha). The test plants are then grown in a greenhouse under optimum conditions. After 3 weeks' test duration, the test is evaluated in accordance with a scale of nine ratings (1=total damage, 9=no action). Ratings of from 1 to 4 (especially from 1 to 3) indicate good to very good herbicidal action.
